Different battery voltage require the different current. We take 12VDC 1000W as an example, in the state of 10VDC, 1000W inverter calculation work formula is: output power / battery voltage = current , that is: I="P/U:" 100A="1000W/10V," the inverter considered has conversion efficiency, BP series inverter, 12VDC conversion efficiency is 88%, the voltage at the battery end is 100Amp/0.88=133.6A.

Should I disconnect my RV battery when plugged in?
It depends on the design of the electrical system in your RV, especially the selection and design of the AC charging and inverter determine if that operation is needed. RV owners need to use the AC equipment in the car when they stay in the car, especially in summer, the temperature inside is very high and it needs to turn on the air conditioner for a long time, but many owners have refrigerators running 24 hours; this time the battery will not be enough, the power of the solar system in the RV is limited, or there is not always good sunshine to support the power generation, then it will be necessary to plug in the mains in the premises or basic to charge the battery and powering the load at the same time. In this case, should I disconnect my RV battery when plugged in? we need to talk about two cases, which have the difference between inverters with bypass function and DC to AC inverters.
If you need to set up an off-grid solar system, you need to understand your needs first. How much load do you need to power, and how long do you need this system to work for you when there is no external environment (no grid and no solar) to provide power? Only when you understand your needs can you design an off-grid solar system that meets your expectations, and we present here two options to choose from.
1. Separate off-grid solar system,
A. Solar Panel,
B. MPPT solar charge controller,
D. DC to AC power inverter,
2. All-in-one off-grid solar system.
A. Solar Panel,
B. Off grid solar inverter,
An integrated off-grid solar system consists of solar panels, an integrated off-grid solar inverter and batteries. The cost will be higher, but easy to install.
